Self-inspection device and test method for deep space detector radio frequency test system

Abstract

The invention provides a self-inspection device for a radio frequency test system of a deep space detector, including a simulation monitoring module, which controls the operation of each functional module and monitors the working state; a CPCI bus, which is used for the interconnection and data interaction of each module; and a down-conversion module , to receive the input uplink signal and perform frequency conversion processing; the intermediate frequency receiving module receives and demodulates the intermediate frequency modulation signal; the remote control signal processing module processes and sends the remote control subcarrier signal; the ranging signal processing module processes and sends the ranging tone signal; the baseband The data processing module processes and sends the analog telemetry data output by the simulation monitoring module; the intermediate frequency modulation module processes and sends the analog telemetry data and ranging tone signals; the up-conversion module up-converts the intermediate frequency modulation signal and outputs downlink signals. The invention can avoid the abnormal communication between the deep-space detector and the ground radio-frequency test system and the potential safety hazard of the deep-space detector caused by improper setting of the ground radio-frequency test system during the test of the deep-space detector.

Description

technical field [0001] The invention relates to the technical field of spacecraft testing, in particular to a self-checking device and a testing method for a radio frequency testing system of a deep space probe. Background technique [0002] Sufficient and comprehensive ground testing is an important guarantee for the successful launch and normal in-orbit operation of a spacecraft. During the ground testing process of a spacecraft, test safety is the most basic requirement. One of the requirements to ensure the safety of the test is to avoid the safety problems caused by the ground test equipment. Therefore, before interconnecting the spacecraft and the ground test system, it is necessary to conduct a sufficient self-inspection on the ground test system to ensure that the spacecraft and the ground The interface between the test systems is safe, and it also ensures the normal function of the ground test system. An important aspect of the self-inspection of the ground test sy...
